Mine is a Delica 4, used to cut wood shavings for firemaking purposes. Been trying out a bunch of different firemaking variations that I've read about here, and I'm happy with the results from wood shavings as the starter. The delica is my first Spyderco and using it has convinced me to invest on more of their knives. Looking at a Native for EDC and a serrated Endura 4 to carry in the woods.
